100

What are the lateral ventricles separated by ?

Each ventricle separated by septum pellucidum 

100

WHat is the location of the third ventricle? 

Located between two thalami

100

How many recesses would the 4th ventricle have? Name them

  • Two lateral dorsal recess
100

What can in be divided into ? 

ANS and Limbic system

200
What is congenital hydrocephalus?

Congenital hydrocephalus is also known as Non-communicating hydrocephalus and result from obstruction within the ventricles

200

Name the foramen that separates the lateral ventricle from the third ventricle

  • Communicates with third ventricle by interventricular foramen of Monro.
200

Name the 4 recesses of the third ventricle

Pineal

Supra pineal 

Infundibular 

Optic 

200

WHat structures do you expect to find in the upper part of the roof? 

  • Upper part of roof - Formed by two superior cerebellar peduncle and superior medullary velum (white matter) bridges the gap between two peduncles
200

Components of the limbic system

Hypothalamus, hippocampus, amygdala

Other associated areas, ventral tegmental area, cingulate gyrus, basal ganglia, prefrontal cortex. 

300

What is the location of Cerebellomedullary cistern? 

Located in the interval between medulla oblongata and inferior surface of cerebellum

300

What are the parts of the lateral ventricle?

  • Anterior horn
  • Central part or body
  • Posterior horn
  • Inferior horn
300

Communication with the 4th ventricle is via which duct? 

  • Posteroinferior- Communicates with the  4th ventricle through cerebral aqueduct of Sylvius
300

Is the floor of the 4th ventricle divided? 

if yes what divides it

ye 

the median sulcus 

300

Removal of the amygdala would result in what happenning? 

What can the ANS be broken down into? 

Lack of aggression


Sympathetic and parasympathetic

400

What are the contents Cistern of lateral sulcus? 

Middle cerebral artery and veins & fronto-orbital veins

400

What are the boundaries of the anterior horn? 

  • Roof- Anterior part of body of corpus callosum
  • Floor-Rostrum of corpus callosum
  • Medial wall- Septum pellucidum, Column of fornix
  • Anterior wall- Genu of corpus callosum
400

WHat can be found on the floor of the 3rd ventricle?

a. Nuclei of hypoglossal nerve

b. vestibular nuclei

c. nuclei for vagus, glossopharyngeal and cranial accessory nerves

What are 5 effects that activation of the sympathetic nervous system would have? 

dilates the pupils
opens the eyelids
stimulates the sweat glands
dilates the blood vessels in large muscles
constricts the blood vessels in the rest of the body
increases the heart rate
opens up the bronchial tubes of the lungs
inhibits the secretions in the digestive system

500

What are the contents (blood vessels) of superior cistern?

  • Upper triangular part- formed by posterior surface of pons
  • Lower triangular part- formed by upper part of posterior surface of medulla
  • Intermediate part is identified by the presence of transverse arranged fibres --- stria medullaris from arcuate nucleus to opposite cerebellum
500

What are 5 effects stimulation of parasympathetic would cause ?
